Abstract
We report a lithium battery using activated carbon on gas diffusion layer (GDL) electrode as host for lithium polysulfide conversion reaction. The cell operates within 2.8 and 2.1 V and delivers a capacity ranging from 400 mAh g(-1) at 1C to 150 mAh g(-1) at 40C over 100 cycles. These characteristics allow the achievement of high energy and power density, i.e. practically estimated to reach the maximum values of the order of 300 Wh kg(-1) and 12 kW kg(-1), respectively. These values, exceeding those delivered by the conventional lithium ion batteries, make our battery of sure interest for practical applications. (C) 2015 Elsevier Ltd. All rights reserved.
